+Release Notes
+=============
+
+Changes in |csit-release|
+-------------------------
+
+#. VPP PERFORMANCE TESTS
+
+ - **Service density 2n-skx tests**: Added higher NF density tests with
+ IPSec encencryption between DUTs.
+
+ - **AVF tests**: Full test coveraged based on code changes in CSIT core
+ layer (driver/interface awareness) and generated by suite generator
+ (Fortville NICs only).
+
+ - **Hoststack TCP/IP tests**: Major refactor of Hoststack TCP
+ performance tests using WRK generator talking to the VPP HTTP
+ static server plugin measuring connections per second and
+ requests per second.
+
+#. TEST FRAMEWORK
+
+ - **CSIT Python3 Support**: Full migration of CSIT from Python2.7 to
+ Python3.6. This change includes library migration, PIP dependency upgrade,
+ CSIT container images, infrastructure packages ugrade/installation.
+
+ - **CSIT PAPI Support**: Finished conversion of CSIT VAT L1 keywords
+ to PAPI L1 KWs in CSIT using VPP Python bindings (VPP PAPI).
+ Redesign of key components of PAPI Socket Executor and PAPI
+ history. Due to issues with PAPI performance, VAT is still used
+ in CSIT for all VPP scale tests. See known issues below.
+
+ - **General Code Housekeeping**: Ongoing RF keywords optimizations,
+ removal of redundant RF keywords and aligning of suite/test
+ setup/teardowns.
+
+
+#. PRESENTATION AND ANALYTICS LAYER
+
+ - **Graphs Layout Improvements**: Improved performance graphs layout
+ for better readibility and maintenance: test grouping, axis
+ labels, descriptions, other informative decoration.

+List of known issues in |csit-release| for VPP performance tests:
+
++----+-----------------------------------------+----------------------------------------------------------------------------------------------------------+
+| # | JiraID | Issue Description |
++====+=========================================+==========================================================================================================+
+| 1 | `CSIT-570 | Sporadic (1 in 200) NDR discovery test failures on x520. DPDK reporting rx-errors, indicating L1 issue. |
+| | <https://jira.fd.io/browse/CSIT-570>`_ | Suspected issue with HW combination of X710-X520 in LF testbeds. Not observed outside of LF testbeds. |
++----+-----------------------------------------+----------------------------------------------------------------------------------------------------------+
+| 2 | `VPP-662 | 9000B packets not supported by NICs VIC1227 and VIC1387. |
+| | <https://jira.fd.io/browse/VPP-662>`_ | |
++----+-----------------------------------------+----------------------------------------------------------------------------------------------------------+
+| 3 | `CSIT-1498 | Memif tests are sporadically failing on initialization of memif connection. |
+| | <https://jira.fd.io/browse/CSIT-1498>`_ | |
++----+-----------------------------------------+----------------------------------------------------------------------------------------------------------+
+| 4 | `VPP-1677 | 9000B ip4 nat44: VPP crash + coredump. |
+| | <https://jira.fd.io/browse/VPP-1677>`_ | VPP crashes very often in case that NAT44 is configured and it has to process IP4 jumbo frames (9000B). |
++----+-----------------------------------------+----------------------------------------------------------------------------------------------------------+
+| 5 | `CSIT-1591 | All CSIT scale tests can not use PAPI due to much slower performance compared to VAT/CLI (it takes much |
+| | <https://jira.fd.io/browse/CSIT-1499>`_ | longer to program VPP). This needs to be addressed on the PAPI side. |
+| +-----------------------------------------+ |
+| | `VPP-1763 | |
+| | <https://jira.fd.io/browse/VPP-1763>`_ | |
++----+-----------------------------------------+----------------------------------------------------------------------------------------------------------+
+| 6 | `VPP-1675 | IPv4 IPSEC 9000B packet tests are failing as no packet is forwarded. |
+| | <https://jira.fd.io/browse/VPP-1675>`_ | Reason: chained buffers are not supported. |
++----+-----------------------------------------+----------------------------------------------------------------------------------------------------------+
+| 7 | `CSIT-1593 | IPv4 AVF 9000B packet tests are failing on 3n-skx while passing on 2n-skx. |
+| | <https://jira.fd.io/browse/CSIT-1593>`_ | |
